The invention provides a power battery thermal management method, a vehicle control unit, a hydrogen energy vehicle and a storage medium. The method comprises the following steps: enabling the vehicle control unit to carry out initialization control on a battery thermal management controller, performing zero clearing on a timer, and controlling the mode of the battery thermal management controller to be a shutdown mode; judging whether the vehicle is being charged or not, and if the vehicle is being charged, enabling the vehicle control unit to control the mode of the battery thermal management controller to be a vehicle external charging mode; and judging whether the vehicle is in a ready state or not, and if the vehicle is in the ready state, enabling the vehicle control unit to control the mode of the battery thermal management controller to be a vehicle driving mode. The method provided by the invention has the beneficial effects that: the vehicle control unit can accurately judge the current charging or driving state of the vehicle, the vehicle control unit is utilized to control the corresponding operation mode of the battery thermal management controller according to the current state of the vehicle, the battery thermal management controller controls a circulating pump, a refrigerator and the like to work, and the temperature of the power battery is controlled, so that stable and efficient work is guaranteed.

    本发明提供一种动力电池热管理方法、整车控制器、氢能汽车及存储介质,整车控制器对电池热管理控制器进行初始化控制,将计时器清零,控制电池热管理控制器的模式为关机模式;判断车辆是否正在充电,若车辆正在充电,整车控制器控制电池热管理控制器的模式为车辆外接充电模式;判断车辆是否处于ready状态,若车辆处于ready状态,整车控制器控制电池热管理控制器的模式为车辆驱动模式。本发明提出的技术方案的有益效果是:整车控制器可以精确判断车辆当前充电或驱动状态,根据车辆当前状态,利用整车控制器控制电池热管理控制器对应的运行模式,电池热管理控制器控制循环泵、制冷器等工作,对动力电池温度进行控制,保证其稳定高效工作。
